Degree:  Ph.D., Cornell University, 1987

Research Topic:  Cover crops, organic fertilizers, vegetable crops

Overview of Research:  My research is focused on short-term nitrogen cycling and long-term soil quality changes as affected by crop rotations, particularly those including cover crops, as well as the efficacy of commercially available organic N fertilizers.  Current research projects look at the timing of N availability with the application of a range of different sources of N approved for organic crop production in vegetable crops.  I am looking at the relative rate of N availability as it is affected by the growing  season temperature and light changes from early spring though late summer, as well as in greenhouse production in the fall and spring seasons.
